This "Galactic Federation" has supposedly been in contact with Israel and the US for years, but are keeping themselves a secret to prevent hysteria until humanity is ready.
According to retired Israeli general and current professor Haim Eshed, the answer is yes, but this has been kept a secret because "humanity isn't ready."
Speaking in an interview to Yediot Aharonot, Eshed – who served as the head of Israel's space security program for nearly 30 years and is a three-time recipient of the Israel Security Award – explained that Israel and the US have both been dealing with aliens for years.
The 87-year-old former space security chief gave further descriptions about exactly what sort of agreements have been made between the aliens and the US, which ostensibly have been made because they wish to research and understand "the fabric of the universe." This cooperation includes a secret underground base on Mars, where there are American and alien representatives.
But Eshed insists that Trump is aware of them, and that he was "on the verge" of disclosing their existence. However, the Galactic Federation reportedly stopped him from doing so, saying they wished to prevent mass hysteria since they felt humanity needed to "evolve and reach a stage where we will... understand what space and spaceships are," Yediot Aharonot reported.
